Can some please help me solve this please

f(3) = 16 and f(4) = 23

Step-by-step explanation:

Finding f(3) simply means we're finding the value of the function when x = 3, so we can plug 3 in for x in our function:

f(3)

, so now we have:

f(3) = 9 + 7

9 + 7 = 16, so f(3) = 16.

Now we want to find the value of x that makes the function equal 23, so let's set our function equal to 23:

We want to get x by itself in order to find the value, so let's start by subtracting 7 from both sides:

23 - 7 =

23 - 7 = 16, so 16 =

Now, we can take the square root of both sides:

, so now we have:

4 = x

honestly bro aint no one got time to answer these dumb question just do it p***y

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
